A method of ring spinning cotton polyester blended yarn. The method is robust and can be used to manufacture the yarn even from polyester fibers that are produced from recycled materials. A new ring spun cotton polyester yarn is also provided. The yarn has few defects and can be effectively dyed when woven into cloth.

A method for transforming a yarn spinning and/or twisting machine and the yarn spinning and/or twisting machine modified according to the method to increase the height (h) of the balloon region zone (a), between the upper and lower ends thereof is provided. In order to provide the zone with two or more balloon regions (a), with means for feeding (1) the thread (2) using conventional upper guides (3), and means for tensing (4) and rolling (5) the thread (2) onto a lower collection reel (6), includes elimination of the conventional guide means (3); and the incorporation of an additional guide accessory (3′) immediately after the feed means (1), including for example, of a clip (30) or a set of rollers (32) optionally with a conveyor belt (33).

Automatic operation of a ring spinning system containing a ring spinning machine having spinning positions and a winding machine having winding positions. Yarn is spun at one of the spinning positions and wound up to a cop. Values of a parameter characteristic for the operation of the spinning position are determined during the winding of the cop and stored as spinning data that is assigned to the cop. The spinning data assigned to the cop is taken into account when deciding whether to feed the cop after it has been set down to one of the winding positions. The assignment is based on an identification of a point in time of winding of the cop and an identification of the spinning position at which the cop was wound.

Systems for fabricating nanofiber yarn at rates of at least 30 m/min (1.8 kilometers (km)/hour (hr)) using a “false twist” nanofiber yarn spinner and a false twist spinning technique are disclosed. In a false twist spinning technique, a twist is introduced to nanofibers in a strand by twisting the nanofibers at points between ends of the strand. This is in contrast to the “true twist” technique where one end of a strand is fixed and the opposing end of the strand is rotated to introduce the twist to intervening portions of yarn.

A multiple nozzle connection that is connectable to a central suction duct of a textile machine includes a connecting piece configured to connect to a compaction device of the textile machine or to a suction tube device that is in communication with the central suction duct. The connecting piece includes three connections, wherein at least one of the connections is closable by one of the connected compaction device or the connected suction tube device.

The method is used to operate a ring spinning system (1) which contains a ring spinning machine (2) having a plurality of spinning positions (21) and a winding machine (3) having a plurality of winding positions (31). Yarn (92) is spun at one of the spinning positions (21) and wound up to a cop (91). Values of a spinning parameter are determined at different times during the winding of the cop (91) and stored as spinning data. The cop is transported from the spinning position (21) to one of the winding positions (31). At the winding position (31) the yarn (92) is rewound from the cop (91) onto a yarn bobbin (93). Values of a yarn parameter are determined at at least two different times during the rewinding of the cop (91) and stored as yarn data. The spinning data and the yarn data are automatically assigned to each other in such a way that they relate to the same yarn section. Based on the spinning data and yarn data assigned to each other, an intervention is made on the ring spinning machine (2).
